Description
FIELD
The subject matter herein generally relates to electronic devices,
and more particularly to a camera module for an electronic
device.
BACKGROUND
More and more electronic products have integrated circuits directly
bonded to an ACF (anisotropic conductive film). In the related art,
a substrate of the electronic product easily generates gas in high
temperature, high pressure, or other harsh environments, and the
generated gas cannot be discharged, so that bubbles may be
generated between the substrate and the ACF, thereby affecting the
use of the product.

DETAILED DESCRIPTION
It will be appreciated that for simplicity and clarity of
illustration, where appropriate, reference numerals have been
repeated among the different figures to indicate corresponding or
analogous elements. Additionally, numerous specific details are set
forth in order to provide a thorough understanding of the
embodiments described herein. However, it will be understood by
those of ordinary skill in the art that the embodiments described
herein can be practiced without these specific details. In other
instances, methods, procedures and components have not been
described in detail so as not to obscure the related relevant
feature being described. The drawings are not necessarily to scale
and the proportions of certain parts may be exaggerated to better
illustrate details and features. The description is not to be
considered as limiting the scope of the embodiments described
herein.
Several definitions that apply throughout this disclosure will now
be presented.
The term "comprising" means "including, but not necessarily limited
to"; it specifically indicates open-ended inclusion or membership
in a so-described combination, group, series and the like.
Referring to FIGS. 1-2, an embodiment of a camera module 100
includes a substrate 10 and a film 20. The substrate 10 defines a
receiving cavity 12. The receiving cavity 12 includes a bottom
portion 13, and the bottom portion 13 defines an opening 14. A
plurality of sensors 15 is provided around the opening 14, and the
film 20 is attached to the substrate 10 to cover the receiving
cavity 12. The camera module 100 further defines a channel 23 to
allow gas in the receiving cavity 12 to be discharged toward the
film 20.
The camera module 100 provided above defines the receiving cavity
12 in the substrate 10, and the channel 23 communicates with the
receiving cavity 12 so that the gas in the receiving cavity 12 is
discharged through the channel 23 to improve reliability of the
camera module 100.
Referring to FIG. 1, spacers 11 are provided on opposite sides of
the substrate 10 for attaching the film 20. In one embodiment, the
film 20 is attached to the substrate 10 by an indenter (not shown)
to press the film 20 on the spacers 11. It should be noted that the
above-mentioned indenter only presses the opposite sides of the
film 20 on the spacers 11.
The receiving cavity 12 is defined in a middle of the substrate
10.
The sensors 15 are mounted on the bottom portion 13 in the
receiving cavity 12. In one embodiment, the bottom portion 13
surrounds an inner wall of the receiving cavity 12.
The opening 14 is defined in a middle of the bottom portion 13 and
communicates with the receiving cavity 12 to allow external light
to enter the camera module 100 through the opening 14.
The sensors 15 are used for detecting external ambient light and
transmitting a detected ambient light signal to a processor (not
shown). In one embodiment, the sensors 15 uniformly surround the
bottom portion 13. It can be understood that the arrangement of the
sensors 15 is not limited. In other embodiments, the sensors 15 may
be randomly distributed on the bottom portion 13. For example, the
sensors 15 may be disposed at four corners of the bottom portion 13
or at midpoints of four sides of the bottom portion 13.
Referring to FIGS. 2 and 3, the film 20 is attached to the spacers
11 at opposite sides of the substrate 10, and the channel 23 is
defined between the film 20 and the receiving cavity 12. It should
be noted that the film 20 is a conductive film. In one embodiment,
the film 20 is an anisotropic conductive film, but the film 20 is
not limited thereto.
When the camera module 100 is in a high temperature, high pressure,
or other harsh environment, the substrate 10 generates gas, and the
generated gas is discharged from the receiving cavity 12 through
the channel 23. It should be noted that there are many ways to
define the channel 23, as described below.
Referring to FIG. 2, in one embodiment, the film 20 includes a
fixing portion 21 and a communicating portion 22. The fixing
portion 21 is attached to the spacers 11. The communicating portion
22 deviates from an edge of the substrate 10, such that a lower
edge of the communicating portion 22 is higher than a lower edge of
the receiving cavity 12, so that the channel 23 is defined between
the film 20 and the receiving cavity 12 to communicate the
receiving cavity 12 to the outside environment, as shown in FIG.
4.
A distance between the communicating portion 22 and the edge of the
substrate 10 ranges from 20 um to 160 um.
Referring to FIG. 3, in another embodiment, there are two films 20.
One end of each film 20 is attached to the spacers 11 of one side
of the substrate 10, and another end of the film 20 extends a
predetermined distance away from the spacers 11 toward the other
film 20. The channel 23 communicating with the receiving cavity 12
is defined between the two films 20 to communicate the receiving
cavity 12 to the outside environment, as shown in FIG. 5.
Referring to FIG. 6, the present application further provides an
electronic device 200 including the above-mentioned camera module
100. The electronic device 200 may be, but is not limited to, a
video camera, a mobile phone, a tablet computer, a notebook
computer, and the like.
In the camera module 100, the film 20 is attached to the spacers 11
and contacts the sensors 15 to transmit the external light signal
detected by the sensors 15.
The channel 23 is defined between two films 20 or between the film
20 and the substrate 10. When the substrate 10 generates gas, the
gas generated by the substrate 10 is discharged from the substrate
10 through the receiving cavity 12 and the channel 23. The camera
module 100 defining the channel 23 communicating with the receiving
cavity 12 has a low manufacturing cost, and reliability of the
electronic device 200 using the camera module 100 is improved.
The embodiments shown and described above are only examples. Even
though numerous characteristics and advantages of the present
technology have been set forth in the foregoing description,
together with details of the structure and function of the present
disclosure, the disclosure is illustrative only, and changes may be
made in the detail, including in matters of shape, size and
arrangement of the parts within the principles of the present
disclosure up to, and including, the full extent established by the
broad general meaning of the terms used in the claims.
